This question is about haloalkanes and polymers.
Freon-11 is a CFC with the molecular formula CFCl3\text{CFCl}_3CFCl3. In the upper atmosphere, the presence of Freon-11 can lead to ozone depletion.
Explain, with the aid of equations, how Freon-11 can lead to this ozone depletion. Use 'dots' (∙\bullet∙) to show the position of unpaired electrons.
An oligomer is a polymer with a low molecular mass and a small number of repeat units. An oligomer made from 1,2-dichloro-1,2-difluoroethene is used in specialized industrial lubricants.
Draw the repeat unit of this oligomer.
The boiling point of the lubricant can be increased by increasing the number of repeat units. Explain this statement.
A polymer can be made from the monomers:
Draw the structures of these monomers and one repeat unit of the polymer.
